I've got 5 woodland plots that size and smaller, and 4 of them are on ridgetops. None have surrounding trees cut or thinned to allow more sun or minimize leaf litter. And all 5 plots attract and feed deer. So yes there is hope.
A few things are CRITICAL. First is being able to broadcast seed into exposed, loosened soil. Unless you're using a drill, the throw and mow method doesn't do well in these type plots. You have to expose soil and the seed has to be strong enough to root.
Second is lime. Oak leaves are quite acidic. You need the soil pH to be compatible with the seed you're putting down. That means lotsa lime.
Third but not least is broadcasting immediately before a good soaking rain. The rain will beat the seed into the fluffed soil, and nature will do its thing. I've broadcast clovers, grains, brassicas, peas, beans, etc. and they grow plenty well enough to attract deer, and they stay visibly green all through winter. I won't win the heart of a row cropping farmer, but its good enough for deer.
